Abstract
A sealed optical street luminaire having a luminaire housing fitted with a clear, flat lens and provided with an LED light source assembly mounted in the housing. The light source assembly has a heat dissipating LED support member secured to a heat conductive adapter for securement in the luminaire housing. A reflector is secured in the luminaire housing. The LED support member supports LED modules at a predetermined angle and orientation relative to an inner reflective surface of the circumferential wall of the reflector. The heat dissipating LED support member and the heat conductive adapter dissipate heat through the luminaire housing whereby to operate the LED modules at a lower temperature than the critical thermal temperature Tc of the LED modules whereby to achieve lifespan, photometric and colorometric rating of the LED modules.
